We really just hired Indoor Air Quality Solutions, IAQS to get the official report in compliance with government regulations. It was an EPA thing that we had to do to qualify for remediation. My husband and I both already knew what the problem was and the area involved. IAQS confirmed what we already knew and wrote up the report for us. Indoor Air Quality Solutions, also gave us names of companies with the appropriate skills for remediation, but we haven't been able to remedy the problem yet. The first hurdle is getting the roof replaced, and we've run into multiple problems with the roofing company. In any event, the people from Indoor Air Quality Solutions, IAQS were nice and fulfilled our need for a report.
